    • Rayleigh–Bénard convection of a viscoplastic liquid in a trapezoidal enclosure 
      Article dans une revue avec comité de lecture
      AGHIGHI, Mohammad Saeid; ccAMMAR, Amine; MASOUMI, Hamed; LANJABI, A. (Elsevier BV, 2020-08)
      .The objective of this paper is to clarify the role of sloping walls on convective heat transport in Rayleigh–Bénard convection within a trapezoidal enclosure filled with viscoplastic fluid. The rheology of the viscoplastic ...
    • Shrinkage porosity prediction empowered by physics-based and data-driven hybrid models 
      Article dans une revue avec comité de lecture
      ccNOURI, Madyen; ccARTOZOUL, Julien; CAILLAUD, Aude; ccAMMAR, Amine; ccCHINESTA SORIA, Francisco; KÖSER, Ole (Springer Science and Business Media LLC, 2022-03-25)
      Several defects might affect a casting part and degrade its quality and the process efficiency. Porosity formation is one of the major defects that can appear in the resulting product. Thus, several research studies aimed ...
    • Modelling of shrinkage formation in casting by the phase field method 
      Article dans une revue avec comité de lecture
      JALOULI, Zahra; CAILLAUD, Aude; ARTOZOUL, Julien; ccAMMAR, Amine; EL-ABIDI, Ahmed; FETTAH, Ahmed (Springer Science and Business Media LLC, 2021-01-05)
      Most commercial softwares simulating casting process use a scalar field to quantify the shrinkage on final parts. The repartition of this scalar is used to localize shrinkage in the part. In this work, the objective is ...
    • Data-driven model based on the simulation of cracking process in brittle material using the phase-field method in application 
      Article dans une revue avec comité de lecture
      KRIAA, Yosra; ccAMMAR, Amine; ZOUARI, Bassem (Cellule MathDoc/CEDRAM, 2020-12-14)
      Numerical simulations and parametric studies of notched rectangular specimens subjected to dynamic tensile loads were performed. The simulations were based on two-dimensional finite element analysis to predict the brittle ...
    • Viscosity and Rheological Properties of Graphene Nanopowders Nanofluids 
      Article dans une revue avec comité de lecture
      BAKAK, Abderrahim; LOTFI, Mohamed; HEYD, Rodolphe; ccAMMAR, Amine; KOUMINA, Abdelaziz (MDPI AG, 2021-07-29)
      The dynamic viscosity and rheological properties of two different non-aqueous graphene nano-plates-based nanofluids are experimentally investigated in this paper, focusing on the effects of solid volume fraction and shear ...
    • Effect of Shear Flow on Nanoparticles Migration near Liquid Interfaces 
      Article dans une revue avec comité de lecture
      ccDAHER, Ali; ccAMMAR, Amine; HIJAZI, Abbas; BENYAHIA, Lazhar (MDPI AG, 2021-08-31)
      The effect of shear flow on spherical nanoparticles (NPs) migration near a liquid–liquid interface is studied by numerical simulation. We have implemented a compact model through which we use the diffuse interface method ...
    • A separated representation involving multiple time scales within the Proper Generalized Decomposition framework 
      Article dans une revue avec comité de lecture
      PASQUALE, Angelo; ccAMMAR, Amine; FALCÓ, Antonio; PEROTTO, Simona; CUETO, Elías; DUVAL, Jean-Louis; ccCHINESTA SORIA, Francisco (Springer Science and Business Media LLC, 2021-11-26)
      Solutions of partial differential equations can exhibit multiple time scales. Standard discretization techniques are constrained to capture the finest scale to accurately predict the response of the system. In this paper, ...
